After initially announcing Google Assistant’s demise before the end of 2025, Google pushed the deadline to 2026 at the last moment. That countdown has officially begun, with Google emailing users to inform them that Google Assistant will start shutting down on September 4, 2026. In its email to users (via Reddit), Google says that it is transitioning the mobile experience from Google Assistant to Gemini. However, Google Assistant will continue to be available on cars with Google built-in even after the September 4 deadline. Chances are, you have already switched to Gemini, so this transition won’t have much impact when Google flips the switch.
